Abstract

Abstract: Being aimed at the problem of contaminated oil in batch transportation of the same gasoline and diesel on different density condition during product oil flowing through the downhill and uphill, with the help of VOF model, the numerical calculation of threedimensional flow model was established. The influence of contaminated oil from different sequence，density，pipe range on boundary layer region was researched on the uphill and downhill road. The results showed that for uphill pipeline the length of the mixed oil of forward diesel was longer than forward gasoline，and the mixed oil volume of forward diesel was greater than forward gasoline. For downhill pipeline the length of the mixed oil of forward gasoline was longer than forward diesel and the mixed oil volume was greater than forward diesel. During forward the same gasoline and trailing diesel for different density diesel, the smaller density could help reduce mixed oil volume.

摘要： 针对成品油经过上、下坡时同种汽油与不同密度的柴油顺序输送时的混油问题,借助多相流模型,建
立三维流动模型进行数值计算,研究了上、下坡顺序输送时的输送顺序、密度、管长对成品油顺序输送混油的影响。
研究结果表明,上坡时在前行柴油工况下的混油长度大于前行汽油工况下的混油长度,混油量也大于前行汽油工况
下的混油量;下坡时在前行汽油工况下的混油长度大于前行柴油工况下的混油长度,而且混油量也大于前行柴油工
况下的混油量。当前行汽油后行不同密度的柴油时,柴油密度越小越有助于减少混油量。
